Search for Charged Bosons Heavier than theWBoson inpp¯Collisions ats=1800GeV

Abstract

We have searched for new, heavy, charged bosons $W^{\prime }$ through the decay $W^{\prime }\to e\nu$ in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}$ TeV. The data used in the search represent 19.7 p${\mathrm{b}}^{–1}$ collected by the Collider Detector at Fermilab. Limits are placed on $\sigma B(p\overline{p}\to W^{\prime }\to e\nu )$ as a function of $M_{W^{\prime }}$. Assuming standard couplings of the $W^{\prime }$ to fermions, we establish the limit $M_{W^{\prime }}>652\mathrm{}$ GeV ${/c}^2$ (95% C.L.).
